Merry Christmas, Mrs. Macabre

Though the holiday break is a relief from school, identical twins Jane and Catherine Gracey miss their witchy friend, Mrs. Macabre dearly. No amount of snow days could ever replace the magic and wonder of her world of monsters known as the Hallowland. But when Catie is suddenly taken to the mysterious North, Jane must ask the help of Mrs. Macabre and friends- monster and human alike- to rescue her. However, Father Christmas has plans for Catie. Soon she'll have to face a very dangerous question: Is it better to be Naughty or Nice?
